In 2002, McDonald's had a promotion for the relatively new anime series named Yu-Gi-Oh! that was released the previous year on Kid's WB. The CD came with the Mighty Kids meal along with small pack of cards. It contained a piece of software that had music, videos, character bios, etc. The three characters on the CDs are Yami Yugi, Kaiba, and Pegasus. Each CD advertised on the slip cover that it contained songs from Music to Duel By and that the full CD was in stores now.
Each CD contained the song "One Card short". The Pegasus CD had the Panik song (not included on Music to Duel By), I'm back , and an instrumental version of One Card Short. Yami Yugi had Your Move and the TV sized version of the theme song. Kaiba had a Yu-Gi-Oh Rap song (also not included on Music to Duel By) featured in the Toys R Us promo for the anime and No Matter What. All of the songs except One Card Short are about 1:30-2 minutes in length. Some of the audio files seem to have loud pops and crackling sounds. I don't know if that has to do with the CDs' age, condition, or if they were released like that to begin with, but I decided to upload them as they are.
Each CD contains a secret pharaoh's chamber that allowed the user to download music and wallpapers once they found the password. For those who are not that adventurous, I shall reveal the passwords.
Yugi - Duelist
Kaiba - Monster
Pegasus - Grandpa
